## Kopy

For dropshippers and store owners, the slow part of launching is rarely the product decision and almost always the page: titles, descriptions, variants, images, pricing and SEO metadata, rewritten and re-uploaded by hand. Kopy attacks that bottleneck with a URL-driven importer. You give it a product, collection or full store link from a supported platform and it pulls the existing data, lets you edit before committing, and creates the listing in your Shopify catalogue.

Supported sources run well beyond one marketplace: Shopify stores, AliExpress, CJ Dropshipping, Etsy, Amazon, Shein, Alibaba and Temu, with more promised over time. Bulk import matters too, so entire collections or catalogues can move in a few minutes rather than one product at a time. On top of raw copying, Kopy adds an AI copywriting layer to generate product descriptions aimed at conversion, plus native machine translation so the same listing can serve several language markets.

The third pillar is Kopy Protect, a storefront-protection feature that hides or blocks the tooling competitor research apps use to scrape your catalogue. Kopy reports over 15,000 dropshippers using it and roughly 2,500 products imported daily, and prices start at a low monthly fee per store with a three-day free trial that includes the AI features and Kopy Protect.

**Pricing & Plans:** Subscription, billed per month per store, with a 3-day free trial including AI features and Kopy Protect. At audit time the published tiers were roughly Starter/Kopy Basic around $9.99/month, Essential (Basic + AI) around $24.99/month, and Ultimate (Basic + AI + Protect) around $32.99/month, with additional stores at about $4.99/month each. Confirm current pricing on the site.

- **One-click product import:** Paste a product, collection, or whole-store URL from Shopify, AliExpress, Temu, Shein, Amazon, Etsy, Alibaba, or CJ Dropshipping and import in seconds.
- **Bulk and full-store copying:** Move entire catalogues and collections at once; stores with 2,500+ products typically complete in a few minutes.
- **AI product page copywriting:** Generate high-converting product descriptions and improve existing copy with AI instead of writing every page by hand.
- **Native translation:** Translate imported products into other languages so one catalogue can sell across multiple languages and markets.
- **Competitor protection:** Kopy Protect blocks competitor spy tools and scrapers that would otherwise copy your product list and pricing.

**Strengths:** Imports from eight-plus platforms, not just one marketplace; AI copywriting and translation are built into the same import flow; Bulk and full-store import saves hours of manual listing work; Low monthly price with a 3-day free trial that includes premium features

**Limitations:** Requires a Shopify store; it is not a standalone e-commerce platform; Quality of imported content depends on how well the source page is structured; AI copy and translations still benefit from a manual review before publishing

## Sider

Sider's premise is that you should not have to leave the page you are reading to use an AI assistant. Its sidebar overlays the browser, detects the content in view, and responds with chat, summaries, translations or explanations using frontier models from multiple providers. The result is a lightweight research and reading workflow: highlight a paragraph, ask for a simpler explanation, translate a PDF and keep the original in sight.

Recent versions push Sider beyond chat. Sider Hand is a browser agent that works across real websites and uses your logged-in sessions to carry out multi-step jobs such as comparing prices while shopping, filling forms, doing cross-site research or triaging a Gmail inbox. Sider Code goes the other way, letting you instruct changes to a website's appearance or behaviour in plain language and preserving the customisation for next time. A Create module generates images, videos, slides and documents from the same panel.

Pricing moves from a limited free tier to credit-based paid plans aimed at heavier users. Lower plans suit occasional chat, summarisation and translation, while higher tiers add a dedicated cloud computer that keeps the browser agent running around the clock and a larger monthly credit allowance. Sider ships as browser extensions for Chrome and Edge plus desktop and mobile apps for macOS, Windows, iOS and Android, and is used by a very large installed base.

**Pricing & Plans:** Freemium. Free tier available with limited credits; paid plans advertised at roughly US$10/month for occasional use up to around US$100/month at the top tier, with higher credit allowances and a dedicated cloud computer on the upper plans.

- **AI sidebar on any page:** A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
- **Summarise and chat with documents:** Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
- **Translation and read-aloud:** Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
- **Sider Hand browser agent:** Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
- **Sider Code page customisation:** Describe a change in plain words and have Sider restyle or simplify any website, remembering the modification for future visits.

**Strengths:** Works inside the browser you already use, with no context switching; Access to multiple frontier models from one subscription; Strong reading toolkit: PDF chat, YouTube summaries, translation and read-aloud; Increasingly capable agent features for multi-step browser tasks

**Limitations:** Useful credits run out quickly on the free and lower tiers; Model availability and quota rules change over time, so expectations must be checked per plan; Some agent and code features depend on a cloud machine and heavier plans
